PRE-INSTALLATION PLANNING
1. Unit must be placed within bathroom area before completion of door framing or, if preferred, studs may be omitted or knocked-
out to permit unit placement.
2. Review job print and Aquatic rough-in dimensions; verify all key dimensions against actual job conditions .
3. Make sure framed-in alcove is of proper size, square and plumb; check floor for levelness.
4. If fire-rated alcove is required, approved finish material must be in place prior to unit installation to meet fire safety requirements
of local building code and/or FHA/HUD Minimum Property Standards. NOTE: Finished alcove must have interior dimensions
shown on rough-in diagram to permit installation of unit.
5. Foundation materials (industrial plaster, mortar mix, lightweight grout) are mandatory under the bottom of each unit to solidify
for wheelchair support.
6. If dome light will be installed, cut out required area within molded 12” (305mm) sq. flat area in center of dome. Use fine-tooth
or abrasive-grit blade. Cut from inside. Light fixture must have UL label and be water and steam tight.
